Nvidia NVLink: does Vulkan see 2 GPUs as a single big one?

Question

I wonder whether Vulkan automagically sees 2 Nvidia GPUs connected by an NVLink as a single "big" GPU when enumerating the physical devices by vkEnumeratePhysicalDevices , or instead it sees them as two individual GPUs. In any case, is it later possible to make a single logical device out of them by vkCreateDevice?

I don't have two of such GPUs and bridge, so I cannot test this myself.

Best,

Erik
